Geopolymer Cement Concrete Urban Eden UNC Charlotte

Geopolymer Cement Concrete. Concrete is a general term used to describe a mix of different sized aggregates (such as sand and small rocks) held together in a matrix by a binder, also called a cement. Concretes are mixed wet and then dry to form a hard, durable material. The binder used in conventional concrete is called Portland cement.
